Inverters have become an indispensable part of homes and offices, especially in areas prone to frequent power outages. However, a common oversight that significantly impacts their performance is neglecting proper battery maintenance, specifically understanding when and how to refill the water. Many users are unaware that failing to regularly check the water levels can lead to a gradual decline in battery backup and charging efficiency. If the water level drops below the minimum mark, the battery can dry out, severely compromising its performance and lifespan. This means your inverter might offer less backup time and take longer to charge, defeating its primary purpose of providing uninterrupted power.

The frequency of checking battery water largely depends on your inverter usage. If power cuts are infrequent and your inverter sees minimal use, checking the water every 2-3 months might suffice. However, for those who rely heavily on their inverter, especially during extended power outages common in summers, it’s crucial to check the water level every 1 to 1.5 months. Always use only distilled water to refill the battery; regular tap water contains impurities that can damage the battery. Look for the ‘Minimum’ and ‘Maximum’ indicators on your battery; the water level should always be between these two marks. Overfilling can lead to overflow and potential damage, while underfilling can cause the battery to dry out. Always wear gloves and safety glasses when checking the battery and consult an expert if the battery feels unusually hot.
